Details

Description:

When a modifier key (e.g. super, alt, ctrl) is pressed when a webview is open, the wxWidgets program begins to poll the webkitwebprocess at an increased rate, resulting in increased CPU usage for both. This does not go back down to baseline levels.

Additional info:

wxgtk3 3.0.3.1-7

Steps to reproduce:

Run minimal working example. Wait for CPU usage to equilibrate, then press alt while program has focus.

you may need to supply -DwxWidgets_CONFIG_OPTIONS=--toolkit=gtk3 to cmake
